Abstract

The invention relates to the technical field of medical equipment, and provides a freezing device and a tumor ablation device. The device includes a refrigerator; a delivery pipe whose input end is connected to the refrigerator, and whose output end is provided with a spray head; The outside of the spray head, the compression baffle, can be folded and unfolded outside the output end of the delivery tube for adjusting the shape of the expanded frozen pouch; at least two compression baffles are evenly distributed outside the output end of the delivery tube Each of the compression baffles is connected by a flexible film; the compression baffle is connected to the flexible film to form an adjustment plane for adjusting the shape of the freezing pouch after the compression baffle is expanded. The present invention realizes the adjustment of the shape of the frozen pouch by setting the compression baffle, which ensures the full fit between the frozen pouch and the irregular wound surface, and can also operate a single compression baffle according to the needs to perform partial area of ​​the frozen pouch. Adjustment to realize the treatment of wounds from different angles.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a freezing device and tumor ablation equipment. Background technique [0002] Renal cancer accounts for about 2-3% of adult malignant tumors, and is one of the common malignant tumors of the genitourinary system. In recent years, with the popularization of physical examination, local early renal cancer is easy to be found, and the guidelines recommend nephron-sparing nephron tumor resection instead of radical nephrectomy. In the past 20 years, with the continuous development and maturity of minimally invasive and precise laparoscopic techniques in the field of urology, laparoscopic partial nephrectomy has become the standard surgical procedure for localized renal cell carcinoma. However, an unavoidable problem in all organ-sparing tumor resections is "positive margins", which means residual tumors. This situation also occurs in laparoscopic partial nephrectomy. If th...
